When audio signals (music, speech, etc) are detected by your computer's microphone, an analog (or continuous) electrical signal is generated. Computers work with digital data, so...there is a device in most computers called an analog-to-digital converter. This chip (or part of a chip) has the ability to sample the analog signal, calculate its amplitude, and return the value to a program (which the displays it, stores it on disk, mixes it, or does a multitude of other things).

This hardware capability is usually built-in to a computer or is a part of a sound card (like a SoundBlaster, etc), while the program is usually something like a Windows' Sound Recorder, audacity, etc.
